However 1t. Is also ev1dent t.hat. no posit.1ve value

unemployment; at. least. as long as t.he above deaorl bed way of performing cost./henefit. analyses will continua t.o be adopt.ed.
Tf a pos i ti ve va1tie were aot.ually at.t.ached t.o lowering unemployment. , t.his should result. 1 n t.he feaslbilit.y (t.hat. 1 s ,

Tn fact, saylng t.hat. somet.hlng (unemployment) 1 has a value*, Implies t.hat. one is ready t.o g1ve up somet.hlng else

t.hat. one can not. reach them all, one has t.o ł t.rade off' (as

Not.hlng new, as we sald. Do you remember t.he Phillips curve regarded as 'a menu of economlc policies1? Since less unemployment appeared t.o prodnce high er Inf lat.ion rat.es, t.he pollcy maker had to choose bet. we en some point, less of t.he rat.e of unemployment. and some point, morę of the rat.e of Inf latlon; and the act.ual choinę depended -it. was sald- on t.he re lat. ive liportance that. t.he policy maker at.tribut.ed t.o lowering unemployment. in relat.ion wit.h t.he st.abilit.y of prices.
